tracing: function return tracer, build fix

fix:

 arch/x86/kernel/ftrace.c: In function 'ftrace_return_to_handler':
 arch/x86/kernel/ftrace.c:112: error: implicit declaration of function 'cpu_clock'

cpu_clock() is implicitly included via a number of ways, but its real
location is sched.h. (Build failure is triggerable if enough other
kernel components are turned off.)
